![]() ![]() The biggest downsides are (1) their high-frequency current may not be compatible with LED circuits, (2) these currents also suffer from extensive voltage loss compared to magnetic types, (3) a 12-volt electronic transformer must be positioned within about 10 feet of the fixture and (4) electronic transformers are subject to overheating and premature failure. The increased frequency allows the use of a miniature core enabling the transformer to be very small, light and inexpensive. This is especially important for larger capacity transformers.Įlectronic transformers convert the 120-volt current to 12 volts by first increasing the frequency of the current from 60 Hz to as high as 20,000 Hz. VOLT® toroidal cores are more energy-efficient, quieter and cooler than EI laminated-types. Lighting systems with relatively high loads - such as 10 or more fixtures - benefit the most from toroidal cores. Toroidal cores are more efficient, experience less buzz and run cooler but are more expensive to make. These are one solid unit shaped like a donut and have the windings wrapped around the donut, in and out of the donut hole. These are less efficient, run hotter and are noisier than toroidal cores. It transforms a 120-volt current into a low-voltage current (between 12-15 VAC). ![]() This is the more common, less expensive method for manufacturing a core. Every landscape lighting system relies on a low voltage transformer. Laminated/stacked cores (also know as EI type). Laminated or stacked windings have sheets wrapped in copper wire that are then stacked or laminated together to make a core. ![]() There are two types of magnetic landscape lighting transformers. Since the secondary coil has 1/10th the number of windings, it creates a current with 1/10th the voltage. The flow of electricity through the primary coil induces a magnetic field that creates a current in the secondary coil. Low voltage transformers, timers, PVC conduit, wire connectors, mounting hardware, tools and more. The primary coil carries the line voltage (108V to 132V). Using these excellent devices, you will connect LED lights and other lighting systems that will make your home look beautiful. Magnetic transformers use two coils to reduce the voltage from 120 volt down to 12 volts. The best low voltage transformers work by transforming the standard voltage running through your home into a lower voltage AC or DC that will power the outdoor lighting system without blowing them up.
